COFFEE-MILL.

SPECIFICATION forming part of Letters Patent No. 382,742., dated May 15,1888.

Application filed February 8, 1888. Serial No; 263,371. (No model.)

To all whom zit may concern,.-

Be it known that I, JOHN M. WADDEL, a

citizen of the United States, residing at Greenfield, in the county of Highland and State of- Ohio, have invented cert-ain new and useful Improvements in Coffee-Mills; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same, reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of this specification. r

My invention relates to improvements of hand or family coffee-mills.

The object of my invention is to improve the construction of hand-mills now in use so that they will be more durable, less noisy, and

more convenient to use.

The invention consists in the handle for the mill and the combination of the handle with the mill-box and the bearings for the grindingshaft.

Figure l is a sectional view of my improved mill, andFig. 2shows a cross-section of the handle on the line a: w of Fig. 1.

1 is the grinding-shaft; 2, the crank-boss; 5, the crank; 3, the box-handle boss constituting one bearing for the shaft. 4 is the other shaftbearing, which is Ysupported bythe hoppercover part 7.

9 is the hopper, and 8 is its flange, by which it is tted to the top a of the box a b c. The flange is secured by screws 13. Bolts 14. may be used.

10 is the part having the stationary grinding-surface, and 11 is the conical grindingwheel having a conical grinding-surface, and is connected to and supported by the shaft 1.

d is a doorway through which any suitablel receptacle may be passed in which to catch the ground coffee.

The box a b c, hopper 9, part 10, wheel 11, shaft 1, bearing 4, and hoppercover 7, as shown here, have previously been so used. The part 7 may be made 'integral with the hopper-casting, as shown, or may be attached to it or to the top a. A similarly-shapedvcoverpart may be removably attached on the other side of the hopper to complete'the cover.

rllhe handle 6 is preferably made of the shape shown, and where its cross-section on the line x a', Fig. 1, is as shown in Fig. 2, and where the upper end is made integral with a boss, 3, for a bearing for the grinding-shaftl, and the lower end is provided with an extension, 12, which may be secured to the top of the box yby screws, as 13. i

1 shows the hopperA 9 placed eccentric to the box. In case it is placed centrally, the

handle 6 may be ycurved around over the edge -of the top of thebox and have its lower end fastened to the side ofthe box. vThe handle 6 and the cover-part 7 could be made integral, so that both bearings 3 and 4 would be rigidly connected; but the construction shown provides two firm bearings for the grinding-shaft l and prevents the wabbling and `rapid-wear which occur with hand-mills havingonly one bearing.

Such mills not only wear in the shaft-bearing,- but when the shaft runs out of `line one side of the grinding-wheel 11 rubs against the stationary: grinding-surface of the part 10,

which dulls the grinding-surfaces 'and causes' the mill to rattle and soon wear out.

-When using former hand-mills, if the box be placed on a table it cannot be conveniently held stationary by the left hand alone while turning the crank with the right ha'nd, and it is equally awkward to hold such a box in onesA lap.

The handle 6 shown provides a positive hand-hold, whereby the mill may be held steady, whether placed upon a table or held in the lap. v .s

The combination shown provides for 4all of these desirable features in a hand-mill.

Any Suitable known means may be ernployed for adjusting the grinding-surfaces with reference t0 each other.

I claim- In a handcoffee-mill, the combination of the grinding-shaft 1, having a hand-crank, 5, the hopper-cover 7, having a bearing, 4, .the millbox a b c, and the'handle, having the shaftbearing 3 at its upper end and an extension at its lower end for securing it to the box, substantially as set forth.

In testimony whereof I now afx my signature in presence of two witnesses. l
